Sideboard from the Restoration period

Period restoration (1830) in fruit wood (pear) inherited from a great aunt 20 years ago, This buffet has 3 drawers and 3 doors, (left 1 door and right double doors). The furniture is in its juice, it lived but still presents very well. We have always maintained it well with wax. It has not had any parasites for a long time even if it bears the traces of them of yesteryear. It would deserve a small restoration to regain an ease of operation (sliding drawers, closing doors, regluing the back or bottoms of drawers). He suffered from central heating.
